Seems my CPP2 has been acting up lately. It will work fine, then suddenly the display will read "8." and I guess the heater is staying on, walked in on it while it was warming up and it had gone up to about 105*f, had it set for 100.5 (38c). Turned the unit off and on and it read 40.9c. Worked fine for a bit after that, cold water solenoid kicked in almost immediately and brought temps back inline. Fast forward to later; I have it running in the other room on a presoak cycle and I hear the cold water solenoid kick on. I go running into the room and find "8." on the display and the temp is down to 90*c. I quickly turn the faucet to "hot" to get the temp back up (I keep a Kodak color thermometer in the bath to monitor it). Turned the unit off and on again, and everything is normal. Just seems to come and go when it's on, but when it comes, it stays until I power cycle it. Anyone have experience with this?
